It is used chiefly as a primary ingredient of steel, but is also used for many finished products such as pipe fittings and structural castings. However, these products are rarely made directly from blast furnace iron. In most cases, the cold pig iron is re-melted in brick or refractory lined cupolas or malleable iron furnaces. In these lined furnaces the quality and analysis of the iron can be more accurately adjusted and controlled, before casting the metal into final form.
